Abstract (en)

[origin: US2017331536A1] The invention relates to a MIMO-FBMC transmitter/receiver with linear precoding implemented in the frequency domain. In one embodiment, at the transmitter the linear precoding is performed (5251, . . . ,525KN) after filtering and spectral spreading, before the IFFT and combination of FBMC symbols in the time domain, such that the precoding does not introduce interference between data streams. In a second embodiment the linear precoding may be combined with the beamforming at transmission or at reception so as to spatially separate the data streams.

Abstract (fr)

L'invention concerne un émetteur/ récepteur MIMO-FBMC à précodage linéaire implémenté dans le domaine fréquentiel. Dans une réalisation au niveau de l'émetteur, le précodage linéaire est effectué (525 1 ,...,525 KN ) après le filtrage et l'étalement spectral, avant la IFFT et la combinaison des symboles FBMC dans le domaine temporel, de sorte que le précodage n'introduit pas d'interférence entre les flux de données. Dans un second mode de réalisation, le précodage linéaire peut être combiné avec une formation de faisceaux à l'émission ou à la réception de manière à séparer spatialement les flux de données.
